VAPORPROOF HAND PORTABLE Filed June 24, 1927 Patented Oct. 28, 1930UNITED STATES FRANGISC. KOLLATH, OF 'CHTCAGO, ILLINOIS VAPORPROOFHAND'IORTABLE Application filed June 24,

My invention relates to hand portable lamps,and especially to that classcommonly called vapor proof handportables, and which are particularlydesigned for use in places where injurious gases and vapors wouldcorrode the socket contacts and other exposed current carrying parts ofthe ordinary unprotected hand portable, thereby clecreasing theefficiency of the device if not destroying its usefulness entirely.

One of the objects of my invention is to provide a hand portable inwhich all of the elec' trical contacts of the socket and lamp areinclosed in a vapor proof chamber formed by the inclosing globe andhandle;

Another object of my invention is to provide, with a minimum number ofparts, a

cushion support for both globe and lamp, and thereby providing a devicewhich may be subjected to rough usage and careless handling with fullprotection to otherwise easily breakable parts.

Another object is to provide a device which is cheap to manufacture,easy to assemble, and of few parts, and in this connection it will benoted that the device as illustrated consists of only four mainelements, that is, the handle, socket, globe, and guard, and providingwith these few parts, full protection for the device, from both shockand injurious vapors and gases.

Realizing that my invention may be varied in its physical embodimentwithout departing from the spirit of the invention, I desire it to beunderstoodthat the specific construction and form herein shown is to betaken as illustrative and not in a limited sense.

In the accompanying drawings, like portions of the device are designatedby like characters thruout the several figures.

Figure 1 is a side elevation of my invention, with a portion of thehandle, guard, and globe broken away to more effectively illustrate thedetails of construction. a

Figure 2 is a detail sectional view illustrating one form ofconstruction when the globe clamping means is independent of the guard.

Referring now to the drawings in detail, my invention as illustrated,comprises a handle 1 having an enlarged portion 2, with a chamber 1927.Serial No 201,663. I

3 therein to receive the socket 4.' This socket is of theordinarycommercial type and is well known, and therefore it need not bedescribed here except to say that it is of molded insulation and has athreaded shell and center contact therein to receive the lamp. Theconductors 6' are molded or cemented inthe insulas tion to form a gasand vapor proof socket except at the front end where the lamp isinserted. v I

The handle-1 which supports the socket, as

well. as theglobe andguard, consists of 'a single piece of flexible andresilient material, preferably comparatively soft molded rub her, whichabsorbs any shocks or jars inci-j dental torough usage. v a V f Thehandleis provided with an internal collar 7 adapted to'fit intoacorres'ponding annular groove 8 in the socket. 4. On the 'outside ofthehandle and directly over the internal collar 7 is an annular groove 9to accommodate the split clamping ring 10 of the wire guard 11. This'guard is of the usual split construction, the twohalves being sprungapart at the bottom'to receive the handle. The individual wires "12 ofthe guard are welded or otherwise secured to the twohalves of the splitring 10. Q 7 A flange l3 havin g an outwardly extending annular ringportion 14, to-r'eceive the globe 15, formed integral with the handlesThe outwardly extending portions 16 of the guard wires 12 form a seatforthe flange 13 to prevent too great a movement'of the globe due to'theresiliency of the flange,

The annular ring 14 is'internally threaded as shown, to receive theglobe which'is of standarddesignr In the outside of the ring 14, anddirectly over the internallythreaded portion, is an annular groove 17to're'ceive the split ring 18, which, in the preferredform, is fastenedby welding or other suitable means to the 'wires12 ofthe guard.

It will be readily understood, from an inspectio'nof the drawings,thatwhen the socket containing the lamp is inserted in the handle and theglobe is screwed intothe ring 14, split rings 10 and 18 may be clampedin place in their respective grooves by any suitable means such as thescrews 19 and 20, thereby forming an effective gas and vapor proof sealbetween the handle and socket, and also between the annular ring 14,which is integral with the handle, and the globe 15. All this beingaccomplished with a minimum of parts.

A coil spring 21 may be provided, if desired, between the outer end ofthe guard and the globe 15, to prevent undue outward movement of theglobe. This is especially desirable when the split clamping ring 18 isnot fastened to the guard wires, as in the construction shown in themodified form in Figure 2.

Having thus fully described my invention, I claim as new and desiretosecure by Letters Patent:

1. A vapor proof shock absorbing electric lighting device comprising asingle piece of soft rubber having a chamber therein to receive asocket, a socketiin said chamber to support an electric lamp, a globearound said lamp and supported in said rubber, said single piece of softrubber cooperating with said socket and said globe to form a combinedvapor proof and shock absorbing means therebetween, and means forclamping said rubber around said socket and said globe.

' 2. An electric lighting device comprising a handle having'a chambertherein to receive a socket, a snugly fitting socket in said chamber toreceive an electric lamp, a globe around said lamp, and a guard aroundsaid globe, shock absorbing and vapor proofing means between said socketand said globe and supporting said globe, shock absorbing and vaporproofing means between said globe and said guard and supporting saidguard, all of said means being integral with said handle, and a clamp onsaid guard and around said handle and clamping all of said means snug lyaround their cooperating parts.

3. An electric lighting device comprising a handle having a chambertherein to receive a socket, a snugly fitting socket in said chamber tosupport an electric lamp, a globe around saidlamp, shock absorbing andvapor. proofing means between said socket and said globe and integralwith said handle, shock absorbing supporting means extending around saidglobe and integral with said handle, and clamping means for clamping allof said parts in shock absorbing and vapor proofing relation andincluding means cooperating with the globe supporting means to hold saidsupport against longitudinal movement.

In witness whereof, I have hereunto subr V scribed my name.

FRANCIS o. KOLLATH.
